Systems and methods for authorizing third-party authentication to a service

ABSTRACT

Systems and method for authorizing third-party authentication to a service are disclosed herein. As exemplary method includes an online service provider subsystem, which is configured to provide a service, 1) receiving a request from a user to use a third-party authentication service to authenticate the user to the service, 2) directing, in response to the request, the user to authenticate to the third-party authentication service, 3) receiving, from a third-party subsystem that provides the third-party authentication service, a third-party user identifier for the user, 4) requiring the user to verify an identity of the user, and 5) authorizing, based on the verified identity of the user, use of the third-party user identifier to authenticate the user to the service. Corresponding methods and systems are also disclosed.

BACKGROUND INFORMATION

Certain online service providers require authentication of a user before granting the user access to a service provided by the service provider. A common practice is to require the user to provide login information such as a username and password that the service provider may use to authenticate the identity of the user.

It is common for a user of multiple services provided by one or more online service providers to create and manage multiple different usernames and passwords. This can become inconvenient, confusing, and/or burdensome to the user.

Attempts have been made to reduce the number of usernames and passwords that have to be created, maintained, and/or used by a user of multiple services. For example, single-sign-on technologies have been created to allow a single set of user credentials (e.g., a username and/or password) to be used for federated login to a set of services and/or service providers.

For example, a standard known as “OpenID” has been developed to allow third-party authentication to be used by service providers to authenticate users to services provided by service providers. In accordance with the OpenID standard, an OpenID provider generates and maintains a unique identifier for a user. The unique identifier is referred to as the user's OpenID. A service provider may establish a relationship with the OpenID provider and authorize the use of the user's OpenID to authenticate the user to a service provided by the service provider. Thereafter, the user may log in to the service by simply indicating a desire to use the user's OpenID for login and then authenticating (e.g., logging in) to the OpenID provider. Once the OpenID provider authenticates the user, the OpenID provider provides the user's OpenID to the service provider, which may then use the user's OpenID to authenticate the user to the service provided by the service provider.

However, there are concerns about potential security vulnerabilities of the OpenID standard. Consequently, certain service providers may be reluctant to authorize the use of users' third-party OpenIDs to authenticate the users to services provided by the service providers. Such service providers may be more willing to consider authorizing the use of users' third-party OpenIDs for authentication to services if additional security measures were to be implemented in conjunction with authorization of users' third-party OpenIDs. For at least these reasons, there exists a need and/or desire for new and/or improved technologies for authorizing third-party authentication of users to a service.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Systems and method for authorizing third-party authentication to a service are disclosed herein. The exemplary systems and methods described herein implement one or more security measures in conjunction with authorization of third-party authentication to a service.

In certain embodiments, for example, an online service provider subsystem, which is configured to provide a service, 1) receives a request from a user to use a third-party authentication service to authenticate the user to the service, 2) directs, in response to the request, the user to authenticate to the third-party authentication service, 3) receives, from a third-party subsystem that provides the third-party authentication service, a third-party user identifier for the user, 4) requires the user to verify an identity of the user, and 5) authorizes, based on the verified identity of the user, use of the third-party user identifier to authenticate the user to the service. Examples of the service provider subsystem requiring the user to verify an identity of the user and authorizing, based on the verified identity of the user, use of the third-party user identifier to authenticate the user to the service are described herein.

By implementing one or more security measures in conjunction with authorization of third-party authentication to a service, such as by requiring a user to verify an identity of a user such as described herein, the systems and methods described herein may enhance the security associated with third-party authentication to a service. Consequently, service providers may be more willing to consider allowing third-party authentication to services provided by the service providers. This may be beneficial to users of multiple services who wish to use a single set of credentials to log in to the services. In addition, service providers who allow third-party authentication to services may benefit from increased satisfaction among users of the services and/or from enhance security in allowing third-party authentication to the services.

Exemplary systems and method for authorizing third-party authentication to a service will now be described with reference to the drawings.

FIG. 1 illustrates an exemplary service access system 100 (or simply “system 100”) that includes a service provider subsystem 102 configured to provide one or more services for access by a user utilizing a user device subsystem 104. Service provider subsystem 102 may include or be implemented by one or more computing devices of a server-side computing system controlled by (e.g., operated by) a service provider. User device subsystem 104 may include or be implemented by one or more client-side computing devices controlled by (e.g., operated by) a user (e.g., an end user of one or more services provided by service provider subsystem 102). Examples of such user devices include, without limitation, a personal computer, a mobile phone device, a tablet computer, and any other computing device or combination of computing devices configured to access a service provided by service provider subsystem 102.

Service provider subsystem 102 and user device subsystem 104 may communicate using any remote communications technologies suitable to support delivery of and access to a service provided by service provider subsystem 102. Examples of such communication technologies include, without limitation, Global System for Mobile Communications (“GSM”) technologies, Long Term Evolution (“LTE”) technologies, Code Division Multiple Access (“CDMA”) technologies, Time Division Multiple Access (“TDMA”) technologies, Evolution Data Optimized Protocol (“EVDO”) (e.g., “1×EVDO”), radio frequency (“RF”) signaling technologies, radio transmission technologies (e.g., One Times Radio Transmission Technology (“1×RTT”)), Transmission Control Protocol (“TCP”), Internet Protocol (“IP”), Session Initiation Protocol (“SIP”), Real-Time Transport Protocol (“RTP”), User Datagram Protocol (“UDP”), Hypertext Transfer Protocol (“HTTP”), Hypertext Transfer Protocol Secure (“HTTPS”), Ethernet, wireless communications technologies, other suitable communications technologies, and any combination or sub-combination thereof.

Service provider subsystem 102 may provide and user device subsystem 104 may access one or more services by way of a network 106. Network 106 may include any network provided by one or more appropriately configured network devices (and communication links thereto) and over which communications and data may be transported between service provider subsystem 102 and user device subsystem 104. For example, network 106 may include, but is not limited to, a mobile phone network (e.g., a cellular phone network, a 3G network, a 4G network, etc.), a satellite media network (e.g., a broadcasting network, a terrestrial media broadcasting network), a media content distribution network (e.g., a subscriber television network), a telecommunications network, the Internet, the World Wide Web, a wide area network, a local area network, any other network capable of transporting communications and data between service provider subsystem 102 and user device subsystem 104, and/or any combination or sub-combination thereof.

Service provider subsystem 102 may provide any service that may be accessed, by way of network 106, by a user using user device subsystem 104. The service may be provided for free, or may require payment of a fee (e.g., a subscription fee) in order to be accessed by the user. In certain embodiments, service provider subsystem 102 may be configured to provide a service related to distribution of and/or access to media content. For example, service provider subsystem 102 may provide a media content delivery service (e.g., a broadcast, multicast, or narrowcast television content delivery service, a live television streaming service, a video-on-demand service, etc.), an online gaming service, a cloud-based content management service, a remote digital video recorder (“DVR”) service, and/or any other service that may be accessed remotely, by way of network 106, by a user utilizing user device subsystem 104. In certain exemplary implementations, service provider subsystem 102 may provide a remote DVR manager service that may be accessed and used by a user to control operation of a DVR (e.g., a network DVR and/or an end-user DVR located at a customer premises) application, service, and or device.

Service provider subsystem 102 and/or one or more services provided by service provider subsystem 102 may be “online,” which may refer to service provider subsystem 102 being connected to network 106 and/or to the services provided by service provider subsystem 102 being provided over network 106 for remote access by user device subsystem 104 by way of network 106.

Service provider subsystem 102 may be configured to require authentication of a user to service provider subsystem 102 and/or to a service provided by service provider subsystem 102 before granting the user access to the service. The phrases “authenticating a user to a service provided by service provider subsystem 102” and “authenticating a user to service provider subsystem 102” will be used interchangeably herein.

In certain embodiments, service provider subsystem 102 may be configured to generate, maintain, and use data representative of user credentials to authenticate a user. For example, when a user initially registers with service provider subsystem 102, service provider subsystem 102 may require that the user provide user credentials, such as a user identifier (e.g., a username) and password that will be used by service provider subsystem 102 going forward to authenticate the user. These user credentials may be specific to the user, service provider subsystem 102, and/or a particular service provided by service provider subsystem 102. After registration of the user with service provider subsystem 102, the user may provide the same user credentials (e.g., by logging in) for authentication to service provider subsystem 102 to gain access to a service provided by service provider subsystem 102.

While user credentials specific to service provider subsystem 102 and/or a service provided by service provider subsystem 102 may be used to authenticate a user to a service provided by service provider subsystem 102, certain users may want to use other credentials not specific to service provider subsystem 102 or a service provided by service provider subsystem 102 for authentication to the service. System 100 may provide this capability as described herein.

As shown in FIG. 1, system 100 further includes a third-party authentication service provider subsystem 108 (or simply “third-party subsystem 108”) configured to communicate with service provider subsystem 102 and user device subsystem 104 by way of network 106. Third-party subsystem 108 may communicate with service provider subsystem 102 and user device subsystem 104 using any suitable communication technologies, including any of those disclosed herein. Third-party subsystem 108 may include or be implemented by one or more computing devices of a server-side computing system controlled by (e.g., operated by) a third party (e.g., a party other than the service provider controlling service provider subsystem 102 and the user controlling user device subsystem 104). The third-party may include an authentication service provider that operates independently of the service provider controlling service provider subsystem 102. The computing system of service provider subsystem 102 and the computing system of third-party authentication service provider subsystem 108 may be separate and/or operate independently of one another.

Third-party subsystem 108 may provide a third-party authentication service for access and use by service provider subsystem 102. To this end, the service provider operating service provider subsystem 102 and the third party operating third-party subsystem 108 may establish a relationship (e.g., a trusted business relationship) and configure service provider subsystem 102 and third-party subsystem 108 to communicate with one another and/or with user device subsystem 104 in a way that provides service provider subsystem 102 access to the third-party authentication service provided by third-party subsystem 108.

Third-party subsystem 108 may be configured to require authentication of a user to third-party subsystem 108 and/or the third-party authentication service provided by third-party subsystem 108 before granting the user access to the third-party authentication service. The phrases “authenticating a user to a third-party authentication service” and “authenticating a user to third-party subsystem 108” will be used interchangeably herein. In certain embodiments, third-party subsystem 108 may be configured to generate, maintain, and use data representative of user credentials to authenticate a user. For example, when a user initially registers with third-party subsystem 108, third-party subsystem 108 may require the user to provide user credentials, such as a username and password that will be used by third-party subsystem 108 going forward to authenticate the user. These user credentials may be specific to the user, third-party subsystem 108, and/or the third-party authentication service provided by third-party subsystem 108.

In conjunction with the initial registration of the user with third-party subsystem 108, third-party subsystem 108 may generate and maintain data representative of a unique user identifier associated with the user. The user identifier may be in any form that allows a unique user identifier to be created for each user and that may be used to identify the user.

After registration of the user with third-party subsystem 108, the user may provide the same user credentials (e.g., by logging in) specific to the third-party subsystem 108 for authentication to third-party subsystem 108 to gain access to the third-party authentication service provided by third-party subsystem 108. When a user is authenticated to third-party subsystem 108, third-party subsystem 108 may be configured to share the unique user identifier associated with the user with a party that has established a trusted business relationship with the third party. For example, third-party subsystem 108 may send data representative of the unique user identifier associated with the user to service provider subsystem 102 for use by service provider subsystem 102 to authenticate the user to a service provided by service provider subsystem 102.

In certain embodiments, the third party operating third-party subsystem 108 may be an OpenID provider, and third-party subsystem 108 may be configured to provide a third-party authentication service in accordance with a defined OpenID standard and/or protocol. In such embodiments, third-party subsystem 108 may generate and maintain data representative of a unique user identifier in the form of an OpenID associated with a user. Third-party subsystem 108 may be configured to provide the OpenID associated with the user to service provider subsystem 102 for use by service provider subsystem 102 to authenticate the user to a service provided by service provider subsystem 102.

Before service provider subsystem 102 uses a third-party user identifier provided by third-party subsystem 108 to authenticate a user to a service provided by service provider subsystem 102, service provider subsystem 102 first authorizes use of the third-party identifier to authenticate the user to the service provided by service provider subsystem 102. As described herein, service provider subsystem 102 may be configured to selectively authorize a third-party identifier in a way that implements one or more security measures.

To illustrate, FIG. 2 illustrates an exemplary method 200 of authorizing third-party authentication to a service according to principles described herein. While FIG. 2 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, combine, reorder, and/or modify any of the steps shown in FIG. 2. In some examples, one or more steps shown in FIG. 2 may be performed by service provider subsystem 102.

In step 202, service provider subsystem 102 receives a request from a user to use a third-party authentication service to authenticate the user to a service provided by service provider subsystem 102. The request may be received in any suitable way. For example, service provider subsystem 102 may provide a user interface (e.g., a webpage) to user device subsystem 104 for use by the user to interact with service provider subsystem 102. The user interface may include an option configured to be selected by the user to indicate that the user wants to use a third-party authentication service to authenticate to the service provided by service provider subsystem 102. In response to a user selection of the option, user device subsystem 104 may send and service provider subsystem 102 may receive the request of the user to use a third-party authenticated service to authenticate the user to the service provided by service provider subsystem 102.

The user selectable option may be presented in the user interface before or after the user has logged in to and been authenticated by service provider subsystem 102. For example, FIG. 3 illustrates an exemplary graphical user interface (“GUI”) 300 that may be provided by service provider subsystem 102 and displayed by user device subsystem 104 before the user has logged in to service provider subsystem 102. As shown, GUI 300 comprises a login page that prompts the user to enter user credentials in the form of a user identifier and password that are specific to service provider subsystem 102. GUI 300 further includes a user selectable option 302 that may be selected by the user to indicate that the user wants to use a third-party authentication service to authenticate to the service provided by service provider subsystem 102. As another example, FIG. 4 illustrates an exemplary GUI 400 that may be provided by service provider subsystem 102 and displayed by user device subsystem 104 after the user has logged in to and been authenticated by service provider subsystem 102. As shown, GUI 400 may include a user selectable option 402 that may be selected by the user to indicate that the user wants to set up use of a third-party authentication service to authenticate to the service provided by service provider subsystem 102.

Returning to FIG. 2, in step 204, service provider subsystem 102 directs the user to authenticate to the third-party authentication service. Step 204 may be performed in any suitable way. For example, service provider subsystem 102 may generate and send a message to user device subsystem 104 that directs user device subsystem 104 to generate and send a login request message to third-party subsystem 108. In certain examples, this may be performed by service provider subsystem 102 generating and sending a redirect uniform resource locator (“URL”) to user device subsystem 104 that is configured to direct user device subsystem 104 to send a request for a login page to third-party subsystem 108. Additionally or alternatively, step 204 may include service provider subsystem 102 communicating with third-party subsystem 108 to notify third-party subsystem 108 of the request from the user and/or of service provider subsystem 102 directing the user to authenticate to the third-party service. Additionally or alternatively, step 204 may include third-party subsystem 108 communicating with service provider subsystem 102 to verify that a request for a login page from user device subsystem 104 is actually initiated by service provider subsystem 102.

Third-party subsystem 108 may receive the login request from user device subsystem 104 and respond by providing a login page to user device subsystem 104. User device subsystem 104 (e.g., a user device included in user device subsystem 104) may present the login page to the user, who may enter login credentials such as a user identifier and password specific to third-party subsystem 108 into the login page. In response, user device subsystem 104 may transmit data representative of the login credentials entered by the user to third-party subsystem 108. Third-party subsystem 108 may use the login credentials, which are specific to the user and to third-party subsystem 108, to authenticate the user to the third-party authentication service provided by third-party subsystem 108.

In certain examples, the login page provided by a third-party subsystem 108 and displayed by user device subsystem 104 may include an option configured to be selected by the user to grant third-party subsystem 108 permission to share information about the user (e.g., a unique user identifier associated with the user and maintained by third-party subsystem 108) with service provider subsystem 102. For example, FIG. 5 illustrates an exemplary GUI 500 that comprises a login page provided by third-party subsystem 108 for use by the user to log in to the third-party authentication service provided by third-party subsystem 108. As shown, GUI 500 may include a user selectable option 502 that may be selected by the user to grant the third party operating third-party subsystem 108 permission to share user information (e.g., an OpenID of a user) with service provider subsystem 102.

After third-party subsystem 108 has received and used the login credentials provided by the user through the login page to authenticate the user to the third-party authentication service provided by third-party subsystem 108, third-party subsystem 108 may identify, from the login credentials, a unique user identifier (e.g., an OpenID) maintained by third-party subsystem 108 for the user. Third-party subsystem 108 may send data representative of the unique user identifier to service provider subsystem 102.

Returning to FIG. 2, in step 206, service provider subsystem 102 receives the third-party user identifier for the user from third-party subsystem 108. Service provider subsystem 102 may determine that the third-party user identifier is associated with a request to authorize the third-party user identifier for use to authenticate the user to the service provided by service provider subsystem 102. In response to the receipt of the third-party user identifier and the determination that the third-party user identifier is associated with a request to authorize the third-party user identifier for use in authenticating the user to the service, service provider subsystem 102 may perform steps 208-210 of method 200.

In step 208, service provider subsystem 102 requires the user to verify an identity of the user. Service provider subsystem 102 may be configured to require any verification of the identity of the user that has been defined by the service provider operating service provider subsystem 102 to be acceptable to the service provider. In certain examples, verification of the identity of the user may include service provider subsystem 102 determining whether the user is currently authenticated and logged in to the service provided by service provider subsystem 102. If the user has logged in to the service using login credentials specific to service provider subsystem 102 and was logged in to the service when the user selected an option to request third-party authentication to the service, the user may remain logged in to the service when service provider subsystem 102 receives the third-party user identifier for the user from the third-party subsystem 108 in step 206. Service provider subsystem 102 may determine that the user is currently logged in and use this authentication of the user with service provider subsystem 102 by way of user login credentials that are specific to the service provider subsystem 102 to count as verification of the identity of the user with service provider subsystem 102.

In other examples, the user may not be currently authenticated and logged in to the service provided by service provider subsystem 102 when service provider subsystem 102 receives the third-party user identifier for the user from third-party subsystem 108. For example, the user may have selected an option to request third-party authentication to the service provided by service provider subsystem 102 without and/or before logging in to service provider subsystem 102, such as by selecting option 302 in GUI 300 shown in FIG. 3. In such cases, step 208 may include service provider subsystem 102 directing the user to provide login credentials specific to the user and service provider subsystem 102 in order to verify the identity of the user to service provider subsystem 102. Service provider subsystem 102 may receive and validate the login credentials to verify the identity of the user.

To illustrate, FIG. 6 shows an exemplary method 600 of verifying an identity of a user. While FIG. 6 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, combine, reorder, and/or modify any of the steps shown in FIG. 6. In some examples, one or more steps shown in FIG. 6 may be performed by service provider subsystem 102.

In step 602, service provider subsystem 102 generates a unique token linked to the third-party user identifier received in step 206 of method 200. Service provider subsystem 102 may be configured to generate a unique token in any suitable way and/or form. In certain embodiments, service provider subsystem 102 may generate the unique token based at least in part on the received third-party user identifier or a portion thereof. Service provider subsystem 102 maintains data representative of the unique token, the third-party user identifier, and a link between the unique token and the third-party user identifier.

In step 604, service provider subsystem 102 generates a URL that includes the token and an address at which an authorization invocation page provided by service provider subsystem 102 may be accessed. For example, the URL may specify the address at which the authorization invocation page may be accessed and may include the token appended to the address of the authorization invocation page. By including the token in the URL, service provider subsystem 102 may later be able to associate the token to any information sent or received in conjunction with the URL. For example, as described further below, service provider subsystem 102 may link the token included in the URL to user credentials received from a user by way of the authorization invocation page associated with the URL, which link may then be used to associate the correct third-party user identifier linked to the token with a service account that may be identified from the login credentials by service provider subsystem 102.

In step 606, service provider subsystem 102 sends the URL to a user device associated with the user, such as a user device included in user device subsystem 104. The URL may direct the user device to request access to the authorization invocation page. Accordingly, the user device may send a request to access the authorization invocation page to service provider subsystem 102.

In step 608, service provider subsystem 102 may receive, from the user device, the request to access the authorization invocation page. In response, service provider subsystem 102 may provide the authorization invocation page to the user device in step 610. The user device may access and present the authorization invocation page, which may prompt the user to provide login credentials that are specific to the user and service provider subsystem 102 in order to verify the identity of the user. For example, FIG. 7 illustrates an exemplary authorization invocation page in the form of a GUI 700 through which the user may enter login credentials to be used to authenticate the user to service provider subsystem 102. The user may provide user credentials by way of the authorization invocation page, and the user device may send data representative of the login credentials received from the user to service provider subsystem 102.

Returning to FIG. 6, in step 612, service provider subsystem 102 receives, from the user device by way of the authorization invocation page, login credentials specific to the user and the service provided by service provider subsystem 102. In step 614, service provider subsystem 102 validates the login credentials. The login credentials may be validated in any suitable way. For example, service provider subsystem 102 may search a database of login credentials maintained by service provider subsystem 102 for a match to the login credentials received from the user device. If a match is found, service provider subsystem 102 validates the login credentials as being associated with a registered user of the service provided by service provider subsystem 102.

While method 600 illustrates an example of obtaining and using user login credentials specific to service provider subsystem 102 to verify the identity of the user, this is illustrative only. Service provider subsystem 102 may be configured to accept additional or alternative user information to verify the identity of the user in other examples. For instance, service provider subsystem 102 may be configured to obtain and accept a credit card number that matches a credit card number associated with a service account of the user as valid verification of the identity of the user.

To illustrate an example of service provider subsystem 102 providing an additional level of security, in addition to providing an authorization invocation page such as GUI 700 to a user, service provider subsystem 102 may generate and send a code to a particular user device associated with the user, such as a mobile phone operated by the user. Service provider subsystem 102 may identify an address for the mobile phone (e.g., a telephone number for the mobile phone) from a service account associated with the user or by asking the user to provide the address for the mobile phone.

As an example, after performance of method 600 shown in FIG. 6, service provider subsystem 102 may use the login credentials received in step 612 to identify a service account for the user and a mobile phone number associated with the service account. Service provider subsystem 102 may generate and send a code (e.g., a twelve-digit numerical code) to the mobile phone of the user, such as by sending the code in a short message service (“SMS”) message. Service provider subsystem 102 may then provide a code input page to another user device (e.g., a personal computer) included in user subsystem 104 for presentation to the user. The user may use the mobile phone to access the code and the other user device to enter the code into the code input page. The other user device may then send the code input by the user to service provided subsystem 102 for validation. FIG. 8 illustrates an exemplary code input page in the form of a GUI 800 that prompts the user to input the code into a code entry field 802.

By implementing security measures such as requiring the user to verify the identity of the user before authorizing third-party authentication to a service, service provider subsystem 102 may protect against certain potential security problems such as OpenID phishing schemes and/or fake or unrelated OpenIDs such as may be used by spammers.

Returning again to FIG. 2, in step 210, service provider subsystem 102 authorizes, based on the verified identity of the user, use of the third-party user identifier to authenticate the user to the service provided by service provider subsystem 102. Service provider subsystem 102 may be configured to perform this authorization in any way that makes the third-party user identifier usable to authenticate the user to the service provided by service provider subsystem 102.

As an example, FIG. 9 shows an exemplary method 900 of authorizing use of a third-party user identifier for authentication to a service. While FIG. 9 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, combine, reorder, and/or modify any of the steps shown in FIG. 9. In some examples, one or more steps shown in FIG. 9 may be performed by service provider subsystem 102.

In step 902, service provider subsystem 102 uses the login credentials received in step 208 of method 200 to identify a service account associated with the user. For example, when service provider subsystem 102 locates a match for the user login credentials in a database of login credentials, service provider subsystem 102 may identify, from data maintained by service provider subsystem 102, a specific service account associated with the login credentials, which service account is specific to the user associated with the login credentials.

In step 904, service provider subsystem 102 uses the token included in the URL used in step 208 of method 200 (and thereby associated with the login credentials) to identify the third-party user identifier associated with the user (e.g., the same third-party user identifier received in step 206 of method 200). As mentioned, service provider subsystem 102 maintains data representative of the token, the third-party user identifier, and a link between the token and the third-party user identifier. Accordingly, service provider subsystem 102 may use the token, which may be received together with the request to access the authorization invocation page, received together with the login credentials, or otherwise be associated with the login credentials to identify a third-party user identifier that has been linked to the token by service provider subsystem 102, as described above.

In step 906, service provider subsystem 102 links the third-party user identifier to the service account associated with the user such that the third-party user identifier is usable to authenticate the user to the service provided by service provider subsystem 102. The linking may be performed in any suitable way. For example, service provider subsystem 102 may add data representative of the third-party user identifier to the service account.

FIG. 10 illustrates an exemplary service account data record 1000 that includes data associated with a service account and/or the user associated with the service account. As shown, data record 1000 may include user login credentials 1002 that are specific to the user and service provider subsystem 102 and that may be used to authenticate the user to service provider subsystem 102. In addition, service account data record 1000 may include data 1004 representative of a third-party user identifier that is provided by a third-party authentication service and that has been added to the data record 1000 to authorize the third-party user identifier to be used to authenticate the user to the service provided by service provider subsystem 102.

FIG. 11 illustrates an exemplary communications flow 1100 for authorizing third-party authentication to a service according to principles described herein. While communications flow 1100 is described in the context of authorizing an OpenID provided by an OpenID provider for use in authenticating a user to a service provided by service provider subsystem 102, this is illustrative only. Communications flow 1100 may be representative of communications flows associated with authorization of other types of third-party authentications for use in authenticating a user to a service provided by service provider subsystem 102.

In step 1102, service provider subsystem 102 sends a user login request to user device subsystem 104 to request that a user of user device subsystem 104 log in to a service provided by service provider subsystem 102. For example, service provider subsystem 102 may send data representative of a service login page, such as GUI 300 shown in FIG. 3, to a user device included in user device subsystem 104.

In step 1104, a user of user device subsystem 104 opts to log in to the service through a third-party OpenID authentication service. In response, user device subsystem 104 sends a message to service provider subsystem 102 to indicate that the user wants to log in through the third-party OpenID authentication service.

In steps 1106 and 1108, service provider subsystem 102 directs the user to authenticate to the third-party OpenID authentication service, such as described herein. Service provider subsystem 102 may communicate with user device subsystem 104 and/or third-party subsystem 108 to directly or indirectly direct the user to authenticate to the third-party OpenID authentication service. In certain examples, service provider subsystem 102 may be configured to send a message to third-party subsystem 108 to request third-party authentication of the user. In response, third-party subsystem 108 may redirect user device subsystem 104 to a third-party service login page, such as GUI 500 shown in FIG. 5. For example, third-party subsystem 108 may send a redirect URL to a user device within user device subsystem 104 to redirect the user device to request access to the third-party service login page. In other examples, service provider subsystem 102 may be configured to send a redirect message (e.g., a redirect URL) to a user device within user device subsystem 104 to direct the user device to request access to the third-party service login page, such as described herein.

User device subsystem 104 may receive a redirect message and send a request for the third-party service login page to third-party subsystem 108, which may provide the third-party service login page to user device subsystem 104. The user of user device subsystem 104 may provide login credentials, and user device subsystem 104 may transmit the login credentials to third-party subsystem 108 in step 1110.

Third-party subsystem 108 may receive and validate the login credentials to authenticate the user to the third-party OpenID authentication service provided by third-party subsystem 108. Third-party subsystem 108 may then identify and send an OpenID for the user to service provider subsystem 102 in step 1112.

With respect to steps 1106-1112, in certain embodiments, service provider subsystem 102 and third-party subsystem 108 may be configured to communicate with one another and/or with user device subsystem 104 in accordance with a defined OpenID standard and/or protocol.

Service provider subsystem 102 may receive the OpenID for the user from third-party subsystem 108 in step 1112 and respond by requiring the user to verify the identity of the user. For example, service provider subsystem 102 may send an authorization invocation page, such as GUI 700 shown in FIG. 7, to user device subsystem 104 in step 1114. The authorization invocation page may be sent in any suitable way, such as by service provider subsystem 102 sending a redirect URL to a user device within user device subsystem 104, and the user device using the redirect URL to send a request for the authorization invocation page to service provider subsystem 102, which may then send the authorization invocation page to the user device.

The user of user device subsystem 104 may provide user login credentials specific to service provider subsystem 102 (and/or other user information defined to be acceptable to service provider subsystem 102 to verify the identity of the user) through the authorization invocation page, and user device subsystem 104 may send the user login credentials to service provider subsystem 102 in step 1116 for use by service provider subsystem 102 to verify the identity of the user and authorize use of the user's OpenID for authentication to a service provided by service provider subsystem 102. Service provider subsystem 102 may receive and validate the user login credentials, and authorize the OpenID for use in authenticating the user to the service by linking the OpenID to the user's service account maintained by service provider subsystem 102, such as described herein.

In certain embodiments, when service provider subsystem 102 receives a request from a user to log in to a service using a third-party identifier, service provider subsystem 102 may determine whether the user's third-party identifier has already been authorized for use in authenticating the user to the service. If the third-party identifier has not already been authorized, service provider subsystem 102 may further determine whether the user making the request is an existing user registered with service provider subsystem 102 or a new user seeking to register with service provider subsystem 102. Service provider subsystem 102 may perform one or more authentication and/or authorization operations depending on these determinations.

To illustrate, FIG. 12 shows an exemplary method 1200 of processing a user request to log in using a third-party user identifier according to principles described herein. While FIG. 12 illustrates exemplary steps according to one embodiment, other embodiments may omit, add to, combine, reorder, and/or modify any of the steps shown in FIG. 12. In some examples, one or more steps shown in FIG. 12 may be performed by service provider subsystem 102.

In step 1202, service provider subsystem 102 receives a request from a user to use a third-party authentication service to authenticate the user to a service provided by service provider subsystem 102, such as described herein.

In step 1204, service provider subsystem 102 directs the user to authenticate to the third-party authentication service, such as described herein.

In step 1206, service provider subsystem 102 receives the third-party user identifier for the user from third-party subsystem 108 that provides the third-party authentication service, such as described herein.

In step 1208, service provider subsystem 102 determines whether the third-party user identifier is already authorized for use to authenticate the user to the service. For example, service provider subsystem 102 may search a database of service accounts for a matching third-party user identifier. If a match is found, service provider subsystem 102 determines that the third-party user identifier is already authorized for use in authenticating the user to the service and authenticates the user to the service in step 1210. Method 1200 then ends after authentication of the user in step 1210, and service provider subsystem 102 grants the user access to the service.

Returning to step 1210, if a match to the third-party user identifier is not found, service provider subsystem 102 determines that the third-party user identifier is not yet authorized for use in authenticating the user to the service. Following this determination, service provider subsystem 102 determines whether the user making the request is an existing user in step 1212. For example, service provider subsystem 102 may prompt the user to provide input indicating whether the user is an existing or new user. Additionally or alternatively, service provider subsystem 102 may prompt the user to provide a mobile phone number that may be used by service provider subsystem 102 to determine whether the user has a mobile phone service account.

If service provider subsystem 102 determines that the user is not an existing user, processing may proceed to step 1214 in which service provider subsystem 102 creates a new service account for the new user and authorizes use of the third-party identifier to authenticate the new user to the service. For example, service provider subsystem 102 may link the third-party user identifier to the new service account. Method 1200 then ends after step 1214, with the new user having been registered with service provider subsystem 102 and the third-party user identifier for the user authorized for use in authenticating the user to the service. In certain embodiments, in conjunction with the registration of the new user, service provider subsystem 102 may allow the new user to elect whether to create user login credentials specific to service provider subsystem 102.

Returning to step 1212, if the user is determined to be an existing user, processing may proceed to step 1216 in which service provider subsystem 102 requires the user to verify the identity of the user in any of the ways described herein, such as by directing the user to provide user login credentials specific to service provider subsystem 102 and/or other acceptable user information that may be used to verify the identity of the user.

In step 1218, service provider subsystem 102 identifies an existing service account associated with the user, such as described herein.

In step 1220, service provider subsystem 102 authorizes, based on the verified identity of the user, use of the third-party user identifier to authenticate the user to the service, such as described herein. For example, service provider subsystem 102 may link the third-party user identifier to the service account identified in step 1218. Method 1200 then ends after step 1220, with the third-party user identifier for the user authorized for use in authenticating the user to the service.
